Question

a. citric acid cycle
b. glycolysis
c. pyruvate oxidation
d. oxidative phosphorylation

Answer 1

The stage of aerobic cellular respiration that generates the most ATP is:

d. oxidative phosphorylation.

During oxidative phosphorylation, which includes the electron transport chain and chemiosmosis, the majority of ATP is produced—typically around 26 to 28 ATP molecules from one glucose molecule, depending on the efficiency of the process and the cell type.
